| چکیده | ||
| This paper contains a strain gradient theory to capture size effects in rotating nanodisks of variable thickness under thermal and mechanical loading. Material properties of nanodisks have been taken homogeneous material. The strain gradient theory and the Hamilton’s principle are employed to derive the governing equations. Due to complexity of the governing differential equation and boundary conditions, numerical schemes are used to solve the problem. In the following, some numerical results are presented to show the influence of size effect on stress analysis of rotating nanodisks. Results show that the stresses of rotating nanodisks is strongly sensitive to the length scale material parameters. | ||
